In any case we have another instance for the misleading headline file on their short article "Greenland's Ice Sheet May Be More Stable than Previously Thought". It could equally read "Antarctica's Ice Sheet Less Stable than Previously Thought". Better would be "Antarctica Drives Greater Fraction of Sea Level Change than Expected".
The press release was titled "Sea Level Rise Less from Greenland, More from Antarctica, Than Expected During Last Interglacial"
The actual article is here: Elizabeth J. Colville, Anders E. Carlson, Brian L. Beard, Robert G. Hatfield, Joseph S. Stoner, Alberto V. Reyes, David J. Ullman. Sr-Nd-Pb Isotope Evidence for Ice-Sheet Presence on Southern Greenland During the Last Interglacial. Science, 2011; 333 (6042): 620-623 DOI: 10.1126/science.1204673
Headlines are important.
